I see too many people crying in chat "Can't 1vs1?!" but we can fix it! Add /duel as a command into FFA gamemode.
Either:
Teleport both players into a duels map and obviously teleport them back afterwards. Why? Because meeting up in the same lobby (and sometimes waiting forever for the arena to generate) would take some time, why not make it quicker? Of course server would have to automatically reserve slots for players duelling (or just make FFA maps have more slots, woohoo!).
Or:
Make all the players disappear for players duelling and vice versa.
